Perioperative change trajectories and predictors of swallowing function and swallowing-related quality of life in patients with oral cancer: a longitudinal observational study.
Observational study in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo determine change trajectories and predictors of swallowing function and swallowing-related quality of life (QoL) in perioperative patients with oral cancer.
designLongitudinal observational study.
settingA tertiary cancer hospital in Hunan Province, China.
participantsPatients with oral cancer scheduled for surgery were recruited using convenience sampling. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were swallowing function and swallowing-related QoL. The secondary outcomes were the predictors of the swallowing function and swallowing-related QoL.
methodsThe participants completed the sociodemographic and clinical data questionnaire, Nutritional Risk Screening 2002 and MD Anderson Dysphagia Inventory before surgery, 7 days after operation and 1 month after operation. Data were analysed using t-test, analysis of variance and generalised linear models.
resultsAmong 138 participants who completed all the three surveys, 41 (29.71%) had moderate to severe dysphagia before surgery. Swallowing function and swallowing-related QoL changed over time, showing the trend of decline first and then increase. Preoperative swallowing function and swallowing-related QoL were affected by sex, lymphocyte level, preoperative nutritional risk and primary tumour site. At 7 days postoperatively, tracheotomy affected swallowing function. At 1 month postoperatively, age and marital status influenced swallowing function, whereas age, type of job and preoperative nutritional risk influenced swallowing-related QoL.
conclusionsOur study demonstrates that perioperative patients with oral cancer generally faced swallowing disorders, especially in the acute phase after surgery. Healthcare providers should pay attention to the swallowing function of perioperative patients with oral cancer, especially those with preoperative nutritional risk, tongue tumour, tracheotomy, age <60 years, and no spouse and the employed patients, and provide available interventions, such as swallowing and nutritional therapy, as early as possible to improve their swallowing function. Meanwhile, doctors should recommend the most evidence-based treatment options, such as reconstruction or not, preoperative chemotherapy or not, to patients.
